GPS for MPAs

September 9, 2021

Question: How do I identify GPS coordinates for Marine Protected Areas (MPAs) when fishing for groundfish at the Farallon Islands off the coast of San Francisco?

Answer: Thanks for your interest in California fishing opportunities, and groundfish. CDFW has two great resources that should help. Our web-based Ocean Sport Fishing Interactive Map allows you to view any area of the state and see the various marine protected areas and other restrictions. If you click or tap on a specific location, more detailed information, including MPA coordinates, will be displayed. When used with a smartphone, the interactive map will show your current position in relation to the various boundaries. Note that this tool requires a cellular or internet connection, so you may need to access it in advance. CDFW is currently working on a truly mobile app that will replace this tool and work outside of cellular range.

Additionally, CDFW has produced printable maps that depict the coastal, island and offshore areas that are open (or closed) to groundfish fishing in 2021. These detailed Rockfish Conservation Area (RCA) Maps show California RCA waypoints and lines, as well as MPAs. Map #11 shows the Farallon Islands.
